|Title||Search for X-ray Counterparts in Pulsar-like High-b Unassociated Fermi Sources|
|Author||Dr J. Eric Grove|
|Description||The Fermi Large Area Telescope has been very successful at discovering gamma-ray pulsars. As we extend the search to dimmer sources, the larger position uncertainty makes discovery more challenging. We propose to observe a set of 6 LAT-detected high Galactic latitude gamma-ray sources that have pulsar-like gamma-ray spectra but no as-yet identified counterparts in any other waveband. These sources have been detected by LAT with high significance and are likely nearby gamma-ray pulsars. The proposed observations are for 20 ks per source, covering the LAT error region in a single pointing. We will determine the X-ray position, flux, and spectral properties for any sources detected by XMM-Newton within this region. This proposal follows successful XMM programs we proposed in Cycles 8 and 9.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
